Hey! I want to use the site Freelancer to post few job ads for things like craiglist posting, etc. I know the site is similar to Odesk and Odesk have hidden 10$ tax when you want to verify your account. I have two questions: 1. How much does it cost to post ads on both sites. 2. When I hire someone, will they automaticaly charge me for that, or we can settle payment(s) differently, because I would like to offer the prospect % from the incomes, not a 'initial fee' or 'monthly payment'. 3. Does Freelancer have verifying tax of 10$( or whatever amount) for verifying your account before you can post ads? In two words - can I post such kind of ad on any of those two sites, how much it would cost me and are there any hidden ways in which they can charge me without my authorization?
